The unique characteristics of an acetic acid/1-methylimidazole (1-MI) mixture, showing higher elec. conductivity than either neat acetic acid or neat 1-MI, yet consisting of elec. neutral mols., are reported. We have applied soft X-ray spectroscopy to reveal the electronic states of acetic acid in the acetic acid/1-MI mixture at various mole fractions of acetic acid (χHOAc). The results show that the amount of acetic acid monomer increases in the region of especially high elec. conductivity and the amount of complex of acetic acid and 1-MI formed by sharing MOs increases in the low elec. conductivity region. There is a little amount of acetic acid monomer in the low elec. conductivity region because the complex inhibits acetic acid from creating its monomer. These results suggest the possibility that the acetic acid monomer is related to elec. conduction. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazole(cas: 616-47-7Reference of 1-Methyl-1H-imidazole)
1-Methyl-1H-imidazole(cas: 616-47-7) is actively involved in removing acid during the production of diethoxyphenylphosphine. It is used as an intermediate in organic synthesis.Reference of 1-Methyl-1H-imidazole
